First off ignore those who who know nothing and think wisdom tooth removal is trivial.
I had mine out in my twenties under local at my dentist. Wish I didn't. Still have bits of tooth left which now thirty years later are starting to play up. I won't frighten you too much but having you gums cut away back with a scalpel, feeling your teeth screwed into, feeling them break up instead of coming out, hearing comments like "Hmm - better leave those bits in - we're starting to pull out bits of bone the bone now" is a bit worrying. Found blood soaked swabs between the cheeks and gums 24 hours later as some feeling started to return. I was on quite strong painkillers for about 3 days. I couldn't talk properly for 24 hours. I could barely open my mouth at first and over two or three weeks normal movement returned - though interestingly I have never been able to get my mouth open as wide after than before.
IMPACTED wisdom tooth removal is a minor surgical procedure.
You might have some difficulty eating and drink for a while afterwards. There might also be stitches to come out if they have to cut into the gums.
On the other hand it depends on individual cases and yours might pop out with no real hassle.
I once worked with someone who had her four wisdom teeth out under a general and she was in a neck collar for weeks afterwards. Seriously.
Vision of a dentist with a knee on her chest, pliers in her mouth tugging, pulling, shaking and shouting "Come out you little bugger..."
I further suggest you don't take the **** with your employers - try and get a weekend in your recovery, don't go back in next day - no one should expect that after a general anaesthetic (sp?) but don't just take a week off if you don't need it.
